  # HEAD: b8c60e8fc6f755c2cdf7164931afdbfa670c6646: selftests/nolibc: add tests for multi-object linkage (2023-10-12 21:14:20 +0200)

----------------------------------------------------------------
nolibc updates for v6.7

o	Add stdarg.h header and a few additional system-call upgrades.

o	Add support for constructors and destructors.

o	Add tests to verify the ability to link multiple .o files
	against nolibc.

o	Numerous string-function optimizations and improvements.

o	Prevent redundant kernel relinks by avoiding embedding of
	initramfs into the kernel image.

o	Allow building i386 with multiarch compiler and make ppc64le
	use qemu-system-ppc64.

o	Miscellaneous fixups, including addition of -nostdinc for
	nolibc-test, avoiding -Wstringop-overflow warnings, and avoiding
	unused parameter warnings for ENOSYS fallbacks.

----------------------------------------------------------------
